According to some embodiments of the present disclosure, auxiliary light can be adopted to irradiate virtual sea to be rendered, this area skill
Art personnel it should be appreciated that the not actual light of the auxiliary light, but fictionalize for determining void to be rendered
Intend the boost line of the rendered color on sea.Specifically, when aiding in light to be radiated on virtual sea to be rendered, can be in institute
State and form point of irradiation on virtual sea to be rendered.Judge the folder between auxiliary light normal corresponding with the point of irradiation
Angle size, and the color of the point of irradiation is rendered according to the corner dimension.
Specifically, the color rendering on virtual sea is described with reference to Fig. 3, wherein, Fig. 3 shows the virtual sea of determination
Rendered color method schematic diagram.
In order to the sunlight for simulating virtual sea reflects color, need at least to configure the first pre-set color and the second default face
Color, wherein, first pre-set color can represent the refraction color of any on virtual sea, and second pre-set color can be represented
The reflection colour of any on virtual sea.Rectangular strip above Fig. 3 is used to represent that the first pre-set color (high order end) is pre- to second
If the gradual change vitta of color (low order end).For arbitrary point on virtual sea, when auxiliary light normal corresponding with point of irradiation it
Between angle level off to 0 ° when, the point of irradiation is rendered using the color of the first pre-set color is leveled off to；Work as fill-in light
Angle between line normal corresponding with point of irradiation level off to 90 ° when, using level off to the second pre-set color color to described

Every bit on virtual sea is carried out after color rendering by said method, obtains as shown in Figure 4 to be rendered
Game effect figure of the virtual sea after normal map is carried out.
In rendering in processing mode for simulation summit wave animation, it is possible to use sea tinter (shader) is to virtual sea
Face carries out being calculated by summit.Specifically, first, for each summit on virtual sea, the normal on the summit can be entered
Row multiple repairing weld, subsequently, according to different abs (sin) function of sampled result establishment direction, speed, frequency and amplitude, Fig. 5
Diagrammatically illustrate the curve map of abs (sin) function.According to some embodiments of the present disclosure, by four direction, speed, frequency

With according to the disposal ability of mobile terminal to being four except quantity in addition to abs (sin) function of quantity be overlapped, not with
This example embodiment is limited.
In rendering in processing mode for foam pinup picture, first, it is determined that whether the height on virtual sea is higher than a preset height,
Wherein, the preset height can be the height determined according to actual displayed effect.Subsequently, in the height for judging virtual sea
In the case of higher than the preset height, virtual sea can be higher by the color of the part mixing foam of the preset height.Fig. 6 shows
Meaning property shows the game effect figure of virtual sea to be rendered after foam pinup picture is carried out.
Processing mode is rendered according to what traditional bloom was processed, it is possible to use Blinn-Phong illumination models formula is calculated
Bloom.
Fig. 7 shows the schematic diagram of the high light reflectivity produced by auxiliary light.With reference to Fig. 7, N is represented on virtual sea a bit
Normal, L represents incident auxiliary light, and R represents reflection light, and V represents that user watches the sight line on virtual sea, H represent L with
The center line of V.The highlight strength of arbitrary point can be expressed as on virtual sea：
Highlight strength=pow (dot (H, N), f)
Wherein, f represents the exhaustion coefficient of bloom.
However, on virtual sea, when normal tiles in a large number, every normal map is actually in the screen of mobile terminal
In occupy less area, cause normal to thicken, have impact on the calculating of bloom.In order to improve such case, according to
Some embodiments of the present disclosure, the exhaustion coefficient f of bloom is preserved into the blue channel of the normal map on virtual sea, by
This, by the high optical index for changing the every bit in the blue channel of normal map, improves the accuracy of high optical oomputing.
However, each pixel is regarded as a normal direction by normal map, and pixel within hardware may be scaled, slotting
Value, causes the normal that final each pixel is represented to there is relatively large deviation with the effect envisioned.
In order to solve the problem, Fig. 8 to show and strengthen the method schematic diagram of normal details accurately to calculate highlight strength.
Wherein, Fig. 8 (a) shows the schematic diagram of the normal of two neighbors, and Fig. 8 (b) shows two adjacent pictures in Fig. 8 (a)
The normal of element merges into the schematic diagram of a pixel.
According to other embodiments of the disclosure, can increase by a third channel, using the third channel described two are strengthened
The rendering effect of individual neighbor.Fig. 8 (c) shows the schematic diagram for strengthening rendering effect using third channel.Furthermore it is possible to match somebody with somebody
Put the first high light factor factor1 and the second high light factor factor2, highlight strength be also denoted as pow (dot (N, L),
Factor1) * factor2, wherein it is possible to control the value of the first high light factor factor1 by third channel.In above formula, because
Dot (N, L) will not have a greater change amplitude, it is possible to change the value of factor1/factor2 to make up due to normal
The error for merging and producing.
Intuitively to represent the effect after bloom is processed, Fig. 9 diagrammatically illustrates virtual sea to be rendered and is carrying out height
Game effect figure after light process.
Realizing the rendering in processing mode of shoal region, at present, by a point of observation to virtual sea any away from
The distance between point distance d2 in seabed on d1 and the point of observation to the same vertical curve of point difference Δ d determines the point
Transparency, specifically, Δ d is closer to 0, and the point is more transparent.However, the method need on virtual sea a little transparent
Degree is calculated, and the GPU bandwidth of mobile terminal is put forward higher requirement, and computation burden is larger.
According to some embodiments of the present disclosure, by an offline depth map calculate between virtual sea and virtual sea bottom away from
From, and the virtual sea on virtual land and virtual sea intersection is arranged according to the distance between virtual sea and virtual sea bottom
Transparency, render process with realize shoal region.
For example, with reference to shown in Figure 10, offline depth map can be that game developer is generated when virtual scene is designed
A gray-scale map (gray scale is top view).Each point in offline depth map have recorded the corresponding height above sea level of point.
Gray-scale map is generally in the range of [0,255], wherein, black is 0, and white is 255.For example, [0,255] corresponding actual height above sea level model
It can be [- 108,20] to enclose, and the altitude ranges show enough the translucent effect of seawater.Advantage using offline depth map exists
In, on the one hand, tinter only need to once be sampled, and then the result after sampling is multiplied by into the i.e. reducible reality of zoom factor
The height above sea level on border, it is not necessary to which each frame copies a depth buffer (depth_buffer), while also without pixel-by-pixel
Linearization calculation；On the other hand, for hardware, the depth map is offline a common pinup picture, and compatibility is preferably.
Figure 11 diagrammatically illustrates the game effect figure in shoal region.Additionally, can also be drawn out using offline depth map
The effect of breakers along ashore, without extra any expense.Specifically, it is possible to use the 3rd of normal map mentioned above
Passage, by the color addition of third channel to virtual sea.Certainly, in other exemplary embodiments of the disclosure, can be with
Breakers along ashore effect is realized by other means, and particular determination is not done to this in this illustrative embodiments.
In rendering in processing mode for configuration inverted image, configuring the method for inverted image can include：First, by shader computations
Go out the screen coordinate on the summit on virtual sea；Then, the screen coordinate on each summit for calculating is converted into the line of inverted image pinup picture
Reason coordinate, to determine the position of inverted image；Secondly, the color of the inverted image pinup picture is sampled, and by the inverted image pinup picture
Color mix with first pre-set color.
According to other embodiments of the disclosure, configuring the method for inverted image can also include：First, by shader computations
Go out the screen coordinate on the summit on virtual sea；Next, the screen coordinate on each summit for calculating is converted into inverted image pinup picture
Texture coordinate, to determine the position of inverted image；Subsequently, during the texture coordinate of the inverted image pinup picture is generated, will be with inverted image
Whether corresponding object blocks the information of bloom writes in a transparent channel, to realize high light blocking.In the method, inverted image patch
Opaque object can block bloom on figure, and transparent object allows bloom to penetrate.For example, virtual sky and the virtual sun are
" all-transparent ", the object of virtual cloud layer and virtual land is considered " opaque ".Such process is hardly
